In this work, hydro ceramsite (HC) was coated by layered aluminum oxyhydroxide (LAO) with the assistance of Iron(III)-alginate (IA) to obtain HC@LAO-IA. Iron(III)-alginate (IA) and layered aluminum oxyhydroxide (LAO) assist in the improvement of the adsorption capacity of hydro ceramsite (HC) for Se(IV), Se(VI), and As(V) via hydrogen bonding, electrostatic adsorption, and inner sphere complexation, respectively. HC@LAO-IA showed superior ...

Highly selective in-situ surface grafting approaches were designed to improve the rejection of 1H-benzotriazole (BTA) by a reverse osmosis (RO) membrane. A commercial FT30 membrane was grafted in-situ for the first time with 2-(diethylamino)ethyl methacrylate (DEAEMA) and 3-(trimethoxysilyl)propyl methacrylate (TMSPMA), respectively, and compared with the state-of-the-art polydopamine (PDA) modification method. The TMSPMA grafting enhanced the ...

Pluripotent stem cell (PSC)-derived cardiomyocytes offer vast potential in heart failure therapy, yet their immaturity poses challenges. To solve this issue, a multifaceted approach combining exclusive biochemical/topographical cues in the design of substrates mimicking the cardiac extracellular matrix was followed. Firstly, polycaprolactone (PCL)/chitosan nanofibers were electrospun in a random and aligned fashion, thus forming myocardium-like ...

The development of a high-performing adsorbent that can capture both iodine vapor from volatile nuclear waste and traces of iodine species from water is an important challenge, especially in industrially relevant process conditions. This study introduces novel imidazopyridinium-based covalent organic frameworks (COFs) through post-modification of a picolinaldehyde-based imine COF. These COFs demonstrate excellent iodine adsorption capacity, ...

Membrane surface functionalization has shown great potential in improving the removal of organic pollutants from water by nanofiltration (NF). However, conventional surface modification methods rely on hazardous chemical solutions and produce large amounts of wastewater, which is contrary to the original purpose of wastewater remediation and the current high demand for environmental sustainability. Herein, we demonstrate a solvent-free and ...

25 years after the first papers on the development of Periodic Mesoporous Organosilicas, and in this special issue in honor of prof. Ozin who stood at the cradle of PMOs, we here report for the first time an "acac-PMO" with the acac-functionality intact and embedded in the organic environment of the linker. Periodic mesoporous organosilicas (PMOs) have emerged as versatile sensors due to their stability, low toxicity, and scalability. This study ...

The total oxidation of methane (CH4), a highly stable alkane volatile organic compound (VOC), using low-cost Cu-based catalysts, has garnered considerable attention. Nonetheless, challenges such as Cu particle agglomeration and the lack of consensus on mechanism of CH4 total oxidation over Cu-based catalysts remain. In this work, β-cyclodextrin (βCD) was introduced during Cu/hydroxyapatite catalyst (βCD-Cu/HAP) preparation, and its catalytic ...

Interfacial polymerization (IP) using m-phenylenediamine and trimesoyl chloride (TMC) is an essential method for producing thin-film composite (TFC) membranes. Nevertheless, IP is highly sensitive to changes in process parameters, especially the TMC solutions flow rate during inside-out TFC hollow fibers (HF) production. Research on the impact of flow conditions (i.e., laminar vs. turbulent flows) of these organic solutions on the final membrane ...

The quest to employ cold plasma sources at atmospheric pressure in polymer processing has emerged as a potent driving force behind their development. Atmospheric pressure operation of plasma jets provides potential cost reductions as well as easier handling and maintenance. In addition, their unique advantage of remote operation allows the substrate to be placed outside the source boundaries. This latter feature makes it easier to process ...
